Hi,
In the current stable release (0.8.1), there are no support to run your code.
We just propose an attach debug and you could eventualy use the eclipse external tools launchconfiguration to run your application. (see the documentation and a tutorial)

The new 0.9.0 version which will be released at the end of the year, will contains a great support of interpreter which will allow you to run your application from LDT.
